UNITED STATES PATENT OFFICE.

ERNEST R. MITCHELL, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO MITCHELL SPECIALTY COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.

cation to doors, easements and similar structures which shall act as a resilient stop or bumper, while at the same time holding the structure to which it is attached from accidental opening, the arrangement of parts being such that my device shall be capable of supporting more or less of the weight of the door or window to which it is attached, or with which it is used.

Another object of the invention is to provide a device of the character described with a resilient roller so mounted as to be capable of frictionally engaging two surfaces atright angles to each other upon the door or frame with which it is used in order that it may not only act totake a certain proportion of the weight of the door off its hinges, but may also act as a stop as well ing means.

These objects and other advantageous ends I secure as hereinafter set forth, reference being had to theaccompanying drawings in which Figure 1 is a perspective view illustrating my invention as applied to a vehicle door; Fig. 2 isa horizontal section of my invention applied to the door shown in Fig. 1; Fig. 3 is a plan of the stamping from which the frame of my device is made; Fig. 4 is a perspective view of the stamping shownin Fig. 3 after it has been formed, but prior to the mounting of the roller therein; and

Figs. 5, 6 and 7 are front, back and end elevations of my invention.

In the above drawings, 1 represents a part of a door frame and 2 a part of a door having a rabbeted edge. On the rabbet of this edge is mounted a metallic body 4 of the construction shown in Figs. 3 to inclusive, in which is mounted a spindle 5 rotatably carrying a rubber roller 6. While I prefer that this spindle shall be so fixed in the;

frame as to be held from rotation,it may be permitted to rotate, and though the roller 6 is preferably of rubber it is obvious that Specification 'of letters Patent.

other suitable material may be employed without departing from my invention.

The body 4 consists of a rectangular piece of sheet metal having punched from it -a central rectangular section so as to provide a hole 7. One side of this piece is then split and the ends formed are bent back along the 11nes aa Fig. 3 through an angle of 90 de-' grees so that they lie parallel to each other, after which they are again bent upon the llnes b-b, causing one edge of each of them to he immediately adjacent and parallel with the adj aeent end of the opening 7. In the two parallel ends 8 thus formed are holes 9 for the reception of the spindle 5 carrying the roller 6 so that its cylindrical surface projects beyond the faeelO of the body as well as beyond the plane of the portions 11.

at right angles thereto. By meansof screws or other suitable holding means, the body is mounted with its face 10 flush with or parallel to the edge of the rabbet 13 and with its parts similarly flush with or parallel to the face 14.- of saidrabbet.

With this construction it is noted that when the door is moved to its closed posias a holdtion, the cylindrical surface of the roller engages the plane face 15 of the door jamb or post and as said door is moved inwardly, is rotated on or with its spindle 5, although more or less compressed, since the parts are so proportioned that the distance between the face 10 of the body 4 and said face of the jamb is less than the amount of projection of the roller beyond said plate. Just before the door reaches its'fully closed position the roller engages the face 16 ofthe rabbet forming part of the door jamb and thus necessarily and without shock brings the door to rest. When in this position, two parts of the surface of the roller lying in planes substantially at right angles to each other are frictionally engaged with the surfaces of the door jamb so that not only is the door held'from moving out of its closed position, but, especially if a plurality of rollers should be employed, there is provided a very material supportfor the door in ad- I dition to that given by its hinges. These sired, as shown in Fig. 2, the face" 15 of the 4 door jamb may-be recessed or under-cut so that the roller will spring into the recess as it approaches its closed position, but this may be omitted without departing from my invention and the face 15 be formed at right angles to the face 16. It is to be understood that it. is immaterial Whether the body 4 and its roller bemounted on the door or on the door jamb since in any case the action above described would be the same. Moreover, while I have described the invention as applied to a door, it will be understood that it may with advantage be applied to various forms of swinging or sliding structures such as windows, either of the casement or sliding sash forms, as Well as to vehicle doors, etc. \Vhile therefore, I have employed the term door in the claims, this is intended to broadly cover closures of various forms as well as other structures, which it is desired, shall be stopped, held and supported as herein specified.

I claim 1. The combination of a frame; a door; a supporting structure mounted on one of said parts; and a resilient roller mounted on said structure with its axis parallel to that of Lemma door in position to simultaneously engage both of said surfaces when the door is closed.

3. The combination of a frame; a door; rabbets respectively formed on two adjacent edges of said door and frame; with a roller mounted on one of said members with its axis parallel to the lines of said edges and in a position for its cylindrical surface to simultaneously and yieldingly engage portions both of the rabbet and of the edge of the other member.

In testimony whereof, l[ have signed my name to this specification, in the presence of two subscribing witnesses.
